Hello !
"a" is an exact number, I suppose?
So Log[a] is exact! If you want a machine-precision result, type : Log[N[a]]
Or, for example : Log[3.0] instead of Log[3] !

Objet : [mg57297] Log function
I have Mathematica 5.0.1. When I attempt to get the Log of a number "a"
by entering Log[a], it does not return the value but echoes back:
Log[a]. How is this fixed?
